Two prototypes entered trials in late
1931,
powered by imported BMW-VI engines. Flight performance was good, and series
production was ordered with domestic M-17 engine. New engine brought
back old problems with cooling...

First ten TSh-2 were finished in
1932,
and production was cancelled in favor of more promising monoplane TSh-3 (TsKB-4)
which was already under development.

In 1932 one of TSh-2 was re-engined with experimental W-engine (three raws of cylinders)
engine M-27. Test flights by Yu.I.Piontkovskij revealed no advantages.
